Abstract
Description
Technical Field
[0001] This utility model belongs to the field of protective netting technology, and in particular relates to a foldable and retractable construction protective netting. Background Technology
[0002] Protective netting is a type of occupational safety tool frequently used in engineering construction. It has a wide range of applications and serves to protect the construction site, isolate pedestrians, prevent non-construction personnel from entering the site, and protect the safety of non-workers. Protective netting is usually composed of connecting posts and a whole piece of netting.
[0003] For example, patent CN222924219U discloses a foldable protective net, including two first net bodies and two second net bodies, one first connecting post and one second connecting post. Sliding bases are slidably disposed at the midpoint of opposite sides of the lower end faces of both the first and second net bodies. Ground nails are fixedly disposed at the midpoint of the lower end faces of multiple sliding bases. Screws are threaded through the front ends of both the first and second connecting posts near their sides. A second handwheel is fixedly disposed at one end of each screw. Multiple locking blocks are fixedly disposed at opposite sides of both the first and second net bodies. In this invention, construction workers can arbitrarily assemble the net using the connecting posts. When not in use, it can be folded using the connecting blocks and folding plates between the net bodies, saving time during transport, making storage more convenient, and saving space.
[0004] Existing foldable construction safety nets are prone to detachment from the connecting posts during use, making them susceptible to tipping over. Therefore, we propose a foldable construction safety net. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a foldable and retractable construction safety net, thus preventing the safety net from easily detaching from the connecting posts.
[0006] In view of this, the present invention provides a foldable and retractable construction safety net, including a column, a limiting rod fixedly connected to the inner wall of the column, a positioning spring sleeved on the outer wall of the limiting rod, a lifting plate fixedly connected to one end of the positioning spring, a push block fixedly connected to the outer wall of the lifting plate, pins fixedly connected to both ends of the lifting plate, a connecting sleeve sleeved on the outer wall of the pin, a protective frame fixedly connected to the outer wall of the connecting sleeve, a protective net body fixedly connected to the outer wall of the protective frame, an unfolding baffle fixedly connected to the outer wall of the column, an unfolding magnet fixedly connected to the inner wall of the unfolding baffle, a folding baffle fixedly connected to the side wall of the column away from the unfolding baffle, and a folding magnet fixedly connected to the outer wall of the folding baffle.
[0007] Based on the above structure, the positioning spring drives the lifting plate to slide vertically along the outer wall of the limiting rod through its own elastic force. The sliding of the lifting plate drives the pin to slide along the inner wall of the column, thereby connecting the pin and the connecting sleeve. This facilitates the quick assembly of the protective frame and the column. When the operator rotates the protective frame in the opposite direction, the protective frame rotates and fits against the outer wall of the folding baffle. The magnetic force of the folding magnet drives the protective frame to fit tightly against the folding baffle, realizing the folding operation of the protective net and facilitating the transfer of the protective net.
[0008] Preferably, two sets of limiting rods are provided, and the two sets of limiting rods are symmetrical about the center of the column. In this embodiment, by providing two sets of limiting rods, it is beneficial to improve the stability of the protective frame connection and prevent the protective frame from falling off.
[0009] Preferably, the pin shaft forms a telescopic structure with the column through a positioning spring and a lifting plate. In this embodiment, the positioning spring drives the lifting plate to slide vertically along the outer wall of the limiting rod through its own elastic force. The sliding of the lifting plate drives the pin shaft to slide along the inner wall of the column, thereby realizing the sliding operation of the pin shaft.
[0010] Preferably, the protective frame is installed with the column through a pin and a connecting sleeve. In this embodiment, the pin and the inner wall of the connecting sleeve are engaged to realize the connection operation of the pin and the connecting sleeve, which facilitates the quick assembly operation of the protective frame and the column.
[0011] Preferably, the unfolding baffle is parallel to the column, and two sets of unfolding baffles are provided. The unfolding baffle is plate-shaped, and the folding baffle has an "L"-shaped cross-section. The folding baffle is perpendicular to the column. In this embodiment, by providing plate-shaped unfolding baffles, it is convenient to unfold and position the protective net body. By providing folding baffles with an "L"-shaped cross-section, it is convenient to fold and position the protective net body.
[0012] Preferably, the protective frame forms an unfolding and fixing structure between the unfolding magnet and the unfolding baffle. In this embodiment, the protective frame rotates and fits against the outer wall of the unfolding baffle. The magnetic force of the unfolding magnet drives the protective frame to fit tightly against the unfolding baffle, thereby realizing the unfolding operation of the protective net.
[0013] Preferably, the protective frame forms a folding and fixing structure through the folding baffle and the folding magnet. In this embodiment, the protective frame rotates and fits against the outer wall of the folding baffle. The magnetic force of the folding magnet drives the protective frame to fit tightly against the folding baffle, thereby realizing the folding operation of the protective net.
[0014] The beneficial effects of this utility model are:
[0015] 1. This foldable and retractable construction safety net, by setting a pin and a connecting sleeve, allows the positioning spring to drive the lifting plate to slide vertically along the outer wall of the limiting rod through its own elasticity. The sliding of the lifting plate causes the pin to slide along the inner wall of the column, so that the pin and the inner wall of the connecting sleeve are engaged, realizing the connection operation of the pin and the connecting sleeve, which facilitates the quick assembly operation of the protective frame and the column.
[0016] 2. This foldable construction safety net, by setting up unfolding magnets and folding magnets, allows the protective frame to rotate and fit against the outer wall of the unfolding baffle. The magnetic force of the unfolding magnets causes the protective frame to fit tightly against the unfolding baffle, thus enabling the unfolding operation of the safety net. Then, the worker rotates the protective frame in the opposite direction, causing the protective frame to rotate and fit against the outer wall of the folding baffle. The magnetic force of the folding magnets causes the protective frame to fit tightly against the folding baffle, thus enabling the folding operation of the safety net, facilitating the transportation of the safety net.

[0026] Based on the above structure, the positioning spring 3 drives the lifting plate 4 to slide vertically along the outer wall of the limiting rod 2 through its own elastic force.
